Compare and Order Whole Numbers

In this topic, we will learn to compare and order whole numbers using two methods - comparing the digits and using a number line.

Topic: Compare Whole Numbers

  • In the case of comparison between numbers containing different number of digits, the number having lesser number of digits is always smaller

  • The number with the greater digit is greater

  • To compare two whole numbers with the same number of digits, we should start comparing the digits of both the numbers one by one from left and stop when we get two different digits

Topic: Order Whole Numbers

  • To arrange the numbers in the order of least to greatest, place all numbers on the number line

  • The numbers on the number line are always arranged in the increasing order from left to right

  • To arrange the numbers in decreasing order, that is from greatest to least, we will arrange them in the order from right to left on the number line
